Bidirectional Storage Installation
A bidirectional storage installation adds a second pair of storage subsystems.
However, the target and initiator roles are reversed from that of the first pair of
storage subsystems. Remote mirroring occurs in both directions with an initiator and
target at each site.
Since the servers have already been configured with host bus adapters, cables,
operating system, and software, configuring the additional storage subsystems is all
that remains.
Repeat the steps in this chapter to configure the second pair of storage subsystems.
IMPORTANT: Remember that the roles of the target and initiator are reversed in bidirectional
storage, so references to them are in the context of the additional pair of storage subsystems
and will be the opposite of the first storage subsystem installation. For example, the target site
during the installation of the first pair of storage subsystems is now the initiator site for the
second pair.
For a bidirectional storage installation perform the following procedures outlined
earlier in this chapter:
1. “Configuring the Controllers at the Target Site”
This refers to the controllers in the newly added storage subsystem. Complete all
these steps.
2. “Configuring the Storage at the Target Site”
3. “Connecting Fiber Optic Cables Between the Controllers and Switches”
4. “Configuring the Controllers at the Initiator Site”
This refers to the controllers in the newly added storage subsystem. Complete all
of these steps.
5. “Configuring the Storage at the Initiator Site”
6. “Connecting Fiber Optic Cables Between the Controllers and Switches”
7. “Creating Remote Copy Sets”
